52.5 The water level will be near the top of the levee which is 53 feet at its lowest point.
50 Water will reach the base of the Texas Pacific railroad bridge girders.
48 The water level will reach the grade level of the lowest elevation on the back side of the Melville ring levee.
45 Considerable flooding occurs.
41 Flooding will begin on the river side of the river levee and on the river side of the Melville protection ring levee. Increased river current will make navigation more difficult and increase the need for strict traffic regulation.
36 Flooding of structures on the unprotected side of the levee begins along Trestle Street and River Bank Road in Melville.
34 Lowest structures on the unprotected side of the levee begin to flood. Flooding is more extensive just south of melville.
33 Action stage.
30 Increased current in the atchafalaya main channel will cause minor navigation problems for large craft, but hazardous conditions for smaller river craft. The average elevation within the protection of the melville ring levee is 31 feet.
25 Flooding will begin on the river side of the atchafalaya river levee and the melville ring levee which protect the city to a river stage of about 50 feet.
